I haven't read read all the post, but here is the fix for the origional thread. The issue is caused by the purge valve for the vapor seperator. It is an EPA required item. The valve must be pluged in correctly or you will have a fault. This valve is suppose to shut off fuel vapor emmissions when the motor is not running. The only problem is that the valve could be of a better quality. Corrective action in case of break down or emergency is to remove the vent line to the vapor seperator, reprime the fuel system and off you go. In worst case instances CUT the small silicone rubber line on the vapor seperator. Thanks Martin
